Primary Gougerot-Sjögren syndrome: a dermatological approach

Abstract

Gougerot-Sjögren syndrome (GSS) is a chronic heterogeneous non-organ-specific autoimmune disease, encompassing a wide spectrum of clinical manifestations. It is characterized by a lymphocytic infiltration of the exocrine glands, also called epitheliitis, resulting in xerostomia and keratoconjunctivitis sicca. The skin can also be involved; for example, xerosis is a consequence of epitheliitis. Dermatological consequences of polyclonal reactivity are vasculitis and manifestations of B-cell proliferation vary from plasma cell infiltrates to B-cell lymphoma.
